BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an incandescent socket connector having a beacon module for indoor positioning, and an indoor positioning system using the same. More particularly, the present invention relates to a technology capable of simply building an indoor positioning system at a low cost, by installing a beacon module for indoor positioning in an incandescent socket connector coupled to an incandescent light to make accurate indoor positioning possible.

2. Description of the Related Art

In recent years, an initial Global Positioning System (GPS) technology developed for military use is being widely used for civilian purposes of navigation, measurement, cartography and the like. Also, even a Location Based Service (LBS) using a GPS receiver as a positioning sensor has been commercialized.

But, it frequently occurs that the GPS receiver cannot receive a GPS satellite signal within doors, a metropolitan area of many high-rise buildings, an underground parking lot, a subway, a tunnel and the like. For this reason, there is a problem that the GPS receiver cannot provide consecutive user location information to a user indoors.

To fix this problem, many researches have been made on an indoor positioning technology of installing an Access Point (AP) within a building and enabling the AP to locate a target within doors using a Radio Frequency (RF) signal, and a service based on this. Active researches have been made on wireless indoor positioning technologies using infrared rays, ultrasonic waves and the like in addition to the RF signal.

The RF signal based indoor positioning technology is a technology of locating a target through a relative Received Signal Strength Indication (RSSI) received from a previously installed access point. The infrared ray based indoor positioning technology is a technology in which infrared sensors installed throughout the indoor recognize an infrared device having a unique IDentifier (ID) code and locate the infrared device. The ultrasonic wave based indoor positioning technology is a technology of locating a target using a transfer rate difference between a fast RF signal and a relative slow ultrasonic wave.

However, the aforementioned indoor positioning technologies excepting the ultrasonic wave based indoor positioning technology have a disadvantage of generally not only causing a large measurement error but also requiring very many access points, infrared sensors or the like. Also, because even an error of positioning information measurement is great more than a few meters, many inconveniences of use are caused.

Owing to the characteristic in which an RF signal is difficult to permeate walls, in many cases, the RF signal based indoor positioning technology is difficult to detect an accurate current location of a user within doors and is also difficult to detect an accurate location of the user between floors. Further, owing to a limitation on a basic reception distance of infrared rays, the infrared ray based indoor positioning technology has a problem that service is restrictive, and the cost of system installation and maintenance is very high. Further, the ultrasonic wave based indoor positioning technology enables accurate measurement, but has a problem that the cost of system installation is very high.

That is, the conventional indoor positioning technologies have a problem of having to bear the investment cost for expensive system building, because they cannot implement indoor positioning if an expensive indoor positioning system is not equipped.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

FIGS. 1 and 2 are diagrams illustrating an incandescent socket connector according to an exemplary embodiment of the present invention.

Referring to FIGS. 1 and 2, the incandescent socket connector 100 according to an exemplary embodiment of the present invention includes a power supply unit 110, an Alternating Current/Direct Current (AC/DC) converter 120, and a beacon module for indoor positioning 130. The incandescent socket connector 100 has a base socket part 100 a and a socket connection part 100 b. The base socket part 100 a is formed at an outer and lower part of a housing of the incandescent socket connector 100 and is coupled to a spiral electrode part (E1) of an incandescent lamp (L1). The socket connection part 100 b is protruded and formed at an outer and upper part of the housing of the incandescent socket connector 100 such that the socket connection part 100 b is coupled to a main socket (S1) fixed to a wall of a building and receives applying of a power source from the main socket (S1).

It is desirable that the base socket part 100 a is constructed in a form of a female screw that is screw coupled to the spiral electrode part (E1) of the incandescent lamp (L1), and it is desirable that the socket connection part 100 b is constructed in a form of a male screw that is screw coupled to the main socket (S1).

Accordingly, if the spiral electrode part (E1) of the incandescent lamp (L1) is coupled to the base socket part 100 a of the incandescent socket connector 100, and the socket connection part 100 b of the incandescent socket connector 100 is connected to the main socket (S1), a power source supplied from the main socket (S1) is applied to the spiral electrode part (E1) of the incandescent lamp (L1) through the incandescent socket connector 100 of the present invention and lights up the incandescent lamp (L1).

Operations of the respective constituent elements are described below in detail.

The power supply unit 110 supplies an AC power source, which is input from the main socket (S1), to the spiral electrode part (E1) of the incandescent lamp (L1).

The AC/DC converter 120 receives an input of the AC power source from the power supply unit 110, converts the received AC power source into a DC power source, and supplies a driving power source (for example, a voltage of 5 Voltage (V)) to the indoor positioning beacon module 130.

The indoor positioning beacon module 130 periodically wireless transmits a beacon signal including a beacon IDentifier (ID) to the external through a built-in antenna (not shown).

Here, the indoor positioning beacon module 130 can periodically wireless transmit a beacon signal including a beacon ID through all available wireless communication networks such as a Wireless Fidelity (WiFi) communication network, a Bluetooth communication network, a Zigbee communication network, a Long Term Evolution (LTE) communication network, a 3-Generation (3G) communication network and the like.

That is, the incandescent socket connector 100 of the present invention applies the power source supplied from the main socket (S1), to the spiral electrode part (E1) of the incandescent lamp (L1) to light up the incandescent lamp (L1), while also playing a role of periodically wireless transmitting the beacon signal including the beacon ID to the external.

FIG. 3 is a diagram illustrating an indoor positioning system according to an exemplary embodiment of the present invention.

Referring to FIG. 3, if an incandescent socket connector 100 of the present invention wireless transmits a beacon signal including a beacon ID to a portable terminal 500, the portable terminal 500 carried by a user within doors receives the beacon signal from the incandescent socket connector 100 located around the portable terminal 500 through wireless communication.

Here, the portable terminal 500 refers to a terminal capable of, in a state where an indoor positioning application is executed, transmitting/receiving various data with the incandescent socket connector 100 and an indoor positioning server 900 through the wireless communication. The portable terminal 500 can be any one of a tablet Personal Computer (PC) in which the wireless communication is possible and application installation is possible, a smart phone, a Personal Digital Assistant (PDA), and a mobile communication terminal. And, the portable terminal 500 can receive beacon signals from one or more incandescent socket connectors 100, respectively, because one or more incandescent socket connectors 100 can be located around the portable terminal 500. And, one or more incandescent socket connector 100 can be located around the portable terminal 500 and therefore, the portable terminal 500 can receive beacon signals from the one or more candescent lamp socket connectors 100, respectively.

The portable terminal 500 receiving the beacon signal extracts the beacon ID from the received beacon signal, detects a strength of the beacon signal, and stores the extracted beacon ID and the detected signal strength in a memory (not shown). The portable terminal 500 periodically includes the beacon ID and signal strength stored in the memory in a location estimation message and wireless transmits the location estimation message to the external positioning server 900.

If the portable terminal 500 wireless transmits a location estimation message to the external positioning server 900, the external positioning server 900 receives the location estimation message from the portable terminal 500, determines a location of a user who carries the portable terminal 500 on the basis of information included in the location estimation message, maps the determined location of the user on a map, and transmits the mapped location of the user to the portable terminal 500.

In an exemplary embodiment, the positioning server 900 may transmit the location of the user to external systems (e.g., building management systems, fire rescue systems, public institutions, information provision systems and the like).

That is, the present invention can detect an accurate current location of a user who carries a portable terminal using the incandescent socket connector 100 equipped with the indoor positioning beacon module 130 and accordingly, can simply build an indoor positioning system at a low cost compared to the related art.

Further, the present invention can detect an accurate current location of a user who carries a portable terminal on the basis of strengths of beacon signals received from one or more incandescent socket connectors 100. Therefore, when a fire or an emergency occurs within a building, the present invention can rapidly detect location information of users and evacuate the users even without going to check if there are persons within doors one by one, and make possible rapid lifesaving and initial response against the fire or emergency.
